Chapter 364: Found nickel ore

In the Apennine peninsula, the conspiracy continues, and it never stops. In Moa, far away in Cuba, Wiltz found the laterite nickel deposit smoothly according to Marin's instructions.

In order to find the exact location of Moa, the pedestrian Wiltz spent a whole month wandering to the northeast coast of Cuba. After repeatedly comparing the coastline and landing to find the lake described by Marin, Moah's location was finally determined.

Fortunately, the Taino people in Cuba were very friendly. After seeing Wiltz and his party, they did not shoot directly. Wiltz is also a person with many years of work experience. He gave gifts such as salt and bread in a timely manner, which won the great favor of locals.

The Taino people were already gentle and hospitable, and Wiltz knew how to use small things to bring the relationship closer. Therefore, Wiltz quickly established a foothold in Moa. With the enthusiastic help of the Taino people, Wiltz quickly led people to build a residential house and settled down locally. Of course, the requirements of the Tylenos are-often bring them salt.

In fact, Wiltz was also quite speechless about the Taino's lack of salt. Why? The Taino people live by the sea. It is a pity that the Taino people in Cuba are less civilized and can only fish in canoes or hunt with earthen arrows. Of course, a little cassava is grown, but the cultivation technique is extremely extensive. Although living by the sea, the salt of the Taino people requires the brave to drive a canoe and go to the Yucatan Peninsula of Mexico to exchange with the Mexican Indians. Mexicans know how to use clay pots to cook salt, but Mexicans will not teach Taino, otherwise, how can they exchange goods with Taino?

However, driving a canoe to exchange salt in the Yucatan Peninsula is a journey of death. The canoe is too small. If the sea is angry, don't need a big storm. A little bigger storm can swallow the canoe. Therefore, going to the Yucatan Peninsula to find the Maya people to buy table salt is very expensive and often kills people.

Therefore, more than a dozen tribes near Moa held a joint meeting to inform Wiltz-as long as enough salt is provided to local people every year, Wiltz can settle and "dig stone" in the local area, and will get the help of local people. Of course, table salt is not indispensable, and locals will also take out prey or cassava in exchange. It's just that the price should be cheaper, preferably the same as the Maya's price in Yucatan Peninsula. It should be noted that those brave men who canoeed to the Yucatan Peninsula to exchange salt often sold salt back to Cuba, and the price tended to increase several times. After all, they bought it for their lives.

Locals use cassava as a reference for food and trade, and of course, shellfish currency. However, outsiders are unlikely to recognize shell currency. For example, when trading with Mexicans, most of Mexico ’s currency uses cocoa beans as a reference object. When the currencies of the two sides are inconsistent, cassava and oats, which can be used as food, become important references.

In the Yucatan Peninsula, one pound of table salt is exchanged for 5 pounds of cassava. But in Cuba, a pound of table salt can exchange for more than 20 pounds of cassava. Therefore, the local chief requested that if Wiltz can provide them with a large amount of salt for 5 pounds of cassava for one pound of salt, then all his activities in the local area (except for killing) will receive strong support from the locals.

Wiltz knew that Cape Breton Island could provide Cuba with a lot of salt, so he agreed without hesitation. Moreover, Wiltz also promised to provide local people with iron farm tools and bows and arrows to facilitate local people to farm and hunt. In this way, the two sides get along more pleasantly. If it were not for Marin ’s three applications and five orders, the colonists were strictly prohibited from having relations with local women. Perhaps some immigrants had already rolled sheets with local enthusiastic girls. Fortunately, the horrible legend of syphilis and the harsh punishment measures of Marin scared the boys.

After settling down, Wiltz began to lead the team to find nickel ore. Although Marin gave an approximate range, Marinna pointed at random, but it was a very large site. Therefore, Wiltz and others also broke their legs. Fortunately, Wiltz used dark bread as a reward and hired a group of locals as guides, but he did not worry about getting lost in the tropical rain forest.

Although, Marin said it was looking for red soil. However, before it was developed, the island of Cuba was full of dense jungle and lush grass. If you want to find red clay, you have to pick up the vegetation first ...

In this way, Wiltz searched for two weeks before finally finding the clay ...

Fortunately, the clay is easy to recognize, otherwise, Wiltz must be exhausted. After finding the red clay, Wiltz set up the stove immediately and burned the collected red clay with high temperature.

Sure enough, after burning at high temperature, the red clay changes color and becomes green nickel oxide. At the same time, it emits a pungent odor (SO2). After finally finding the nickel ore, Wiltz was so excited that he immediately started mining laterite nickel ore, and began to assemble the furnaces and pipelines on the ship, began to assemble, intending to calcinate laterite nickel ore on a large scale.

According to Marin's plan, Wiltz needed to locally calcinate laterite nickel ore into green nickel oxide and use a desulfurization water tower to collect sulfur dioxide gas.

However, at the beginning of production, the desulfurization system leaked due to pipeline rupture and insufficient attention to desulfurization by construction personnel. The leaked sulfur dioxide gas smoked people enough. Moreover, it also angered the nearby Taino. So the nearby Techno people asked Wiltz to stop making this "terrible gas" ...

Wiltz, who was unsettled, had no choice but to suspend production. Then, he saw the map that Marin gave him, noting that there was an island called Grand Inagua not far from Moa. After thinking over and over again, Wiltz decided to relocate the production process of the calcined laterite nickel ore to Grand Inagua. He came to mine, not to pinch the locals. If possible, it is better to get along peacefully.

Seeing that Wiltz no longer produces that terrible gas (SO2), the Technos no longer have trouble with Wiltz.

After exploration by the crew assigned to the ships used by Wiltz, it was discovered that on the island of Big Inagua, about 100 kilometers away from Moa, the west coast has no population. Moreover, there are many trees on the island, which is very suitable for felling as firewood for the calcination of laterite nickel ore.

In this way, Wiltz divided mining and smelting into two places. Of course, conflict with the local Taino in Moa was also avoided. After the relocation of the refining site, the local Taino people in Moa took the initiative to help dig the laterite nickel mine.

On the west coast of Grand Inagua, Wiltz directed craftsmen to rebuild the smelting system and perfect the water desulfurization system. The forging furnace isolates the air, but has an air inlet driven by a bellows to allow oxygen to enter and react with nickel sulfide to produce nickel oxide and sulfur dioxide.

The sulfur dioxide gas enters the sink along with the pipeline and is absorbed by the water in the sink. Of course, because SO2 is not as soluble as SO3. Therefore, after a period of time, when the water in the tank that absorbs SO2 absorbs enough SO2, a saturated sulfurous acid solution will be formed. At this time, the water in the water tank can no longer absorb SO2. Then, the foul SO2 will overflow. Then, the workers present need to replace the water in the sink in time.

The originally saturated sulfurous acid solution ~ www.wuxiaspot.com ~ was poured into another container, and the workers used wooden sticks to stir, so that enough oxygen could enter the solution and react naturally with sulfurous acid to generate sulfuric acid.

However, this process is very inefficient. Even after a few weeks of trouble, only a small half of sulfurous acid is converted into sulfuric acid.

Moreover, because of the volatilization of water vapor, SO2 gas will leak out, causing workers to inhale SO2 and endanger health. Therefore, Marin requires frequent replacement of workers to avoid long-term inhalation of SO2 by a single person. Moreover, for workers who are responsible for dangerous processes that easily inhale SO2, Marin prefers to use Uncle Black ...

Of course, when activated carbon is produced in the future, Marin will engage in gas masks. In this way, there is no need for anyone to take risks.

As for how to separate sulfuric acid and sulfurous acid? Don't be too simple. Just put the mixed solution in the air and let the water vapor volatilize. SO3 is infinitely soluble in water, as long as there is water, SO3 will stay in the water and will not easily escape. Different from SO2, its volume ratio with water is 40 to 1. As the water vapor evaporates, SO2 will gradually escape. When the water is reduced to a certain level, SO2 will escape almost. Then, the rest is sulfuric acid with higher concentration ...
